GeoMonday 2015.3 – Mobile 3D Mapping with a Low-Cost UAV System

TU_Logo_lang_RGB_rotIn this presentation it is shown how an UAV system can be built at low costs. The components of the system, the equipment as well as the control software are presented. The main focus of this presentation is on the generation of 3D point clouds from digital imagery. For this web services and free software solutions are presented which automatically generate 3D point clouds from arbitrary image configurations. Possibilities of georeferencing are described whereas the achieved accuracy has been determined. The presented workflow is finally used for the acquisition of 3D geodata. On the example of a landfill survey it is shown that marketable products can be derived using a low-cost UAV. At the end of the presentation the latest trends in the UAV market are presented.

NeitzelFrank Neitzel is a Professor for Geo-IT and Geodesy at the Technical University (TU) Berlin. He has a lot of experience in building affordable drones for 3D Geo-data collection and already published related papers.

GeoMonday the 2nd – Talk 1: Buildings in space, sun in time (presentation material)

Jan Marsch started the 2nd GeoMonday and spoke about his project OSM Buildings – an open source JavaScript library for visualizing 3d building geometry.

GeoMonday the 2nd – Talk 1: Buildings in space, sun in time

Jan MarschAs a freelance software engineer Jan Marsch is driving enterprise web applications for a long time. A few years ago he got addicted with maps and is engaged with OSM Buildings – an open source JavaScript library for visualizing 3d building geometry.

In his talk, basing on OSM Buildings, he will add another dimension to OpenStreetMaps data just by algorithms. The discussion covers some details about the concepts, code and pitfalls.
